This paper presents the speed control of a separately excited DC motor using Fuzzy Logic Control (FLC). The  Fuzzy Logic Controller designed in this study applies the required control voltage based on motor speed error (e) and its change (ce). The performance of the driver system was evaluated through digital simulations using Simulink. The simulation results show that the control with FLC outperforms PI control in terms of overshoot, steady state error and rise time.

The conventional line commutated ac-to-dc converters/ inverters have square-shaped line current which contains higher-order harmonics. Moreover, it requires a costly and bulky dc inductor or choke. The line current with the high harmonic contents generates EMI and therefore itcauses more heating of the core of distribution or power transformers. Alternatively, PWM based inverters using MOSFET/IGBT switches can be used for the above purpose. However, apart from higher switching losses, the power...

Fast delay estimation methods, as compared to simulation techniques, are needed for incremental performance-driven layout synthesis. On-chip inductive and conductive effects are becoming predominant in deep submicron (DSM) interconnects due to increasing clock speeds; circuit complexity and interconnect lengths. Inductance causes noise in the signal waveforms, which can adversely affect the performance of the circuit and signal integrity. Elmore delay-based estimation methods, although...

In this paper, a new active snubber circuit is developed for PFC converter. This active snubber circuit provides zero voltage transition (ZVT) turn on and zero current transition (ZCT) turn off for the main switch without any extra current or voltage stresses. Auxiliary switch turns on and off with zero current switching (ZCS) without voltage stress. Although there is a current stress on the auxiliary switch, it is decreased by diverting it to the output side with coupling inductance. The...

This paper solves reliability constrained unit commitment problem (UCP) for a composite power system network using network equivalent technique. Here, the integration of generation and transmission system reliability forms a composite power system model. The inclusion of load forecast uncertainty for the solution of unit commitment problem will give more accurate assessment of spinning reserve (SR). Probabilistic techniques help in setting the reserve requirement which is defined by reliability...

A novel example-based process for automated colorization of grayscale images using texture descriptors (ACTD) without any human intervention is proposed. By analyzing a set of sample color images, coherent regions of homogeneous textures are extracted. A multi-channel filtering technique is used for texture-based image segmentation. For each area of interest, state of the art texture descriptors are then computed and stored, along with corresponding color information. These texture descriptors...

This paper analyzes the probability distribution of wind speed data recorded by Maharashtra Energy Development Agency (MEDA) wind farm at Ahmednagar (India). The main objective is to validate the wind energy probability by using probability distribution function (PDF) of available wind potential. The wind speed is measured with the help of three anemometers S30, S45, S60 placed at 30 m, 45 m, and 60 m height. Mean values are recorded and stored for every hour using a Data logger. For accounting...

Power electronics systems are non-linear systems, which consume more reactive power and also the loads they feed are mostly inductive loads which leads to a poor power factor. Various compensation techniques are available to bring the power factor nearer to unity. In this paper, a novel compensator is proposed, where in-phase and quadrature components of the supply current are vector-controlled. Implementation of this compensator in a power electronic system operating with a very poor power...

Seamless interoperability between two dissimilar networks requires handoff from one network to the other. Such handoffs are known as vertical handoffs. Vertical handoff introduces a shift in the approach to handoffs. It deals with handoffs between dissimilar networks, such as from an access point to a base station or vice versa. The integration of diverse but complementary cellular and wireless technologies in the next generation of wireless communication systems requires the design of...
